"Combining Nature with Art and Container Gardening"

Heat and Humidity Great for Tropicals, but Not So Good for Tomatoes!

This is a big pot at the front of my home exploding right now with tall Canna lilies.

Who doesn’t like Canna lily plants, right?

They are easy to grow, get big and lush, and may be overwintered by storing their rhizomes (tubers), which must be dug up after the tops of the plants are blacked by frost – or just before frost.

Growing them in big pots makes it easier to pull them out by October, thus, why I am going to show the process in early September so you may learn it if desired. (See dates below on that if interested.)

They also thrive in the heat, humidity, and rain, which we are getting all week. None of these weather conditions are harming their attitudes at all – they love it.

My tomato plants, however, are a different story right now.

They started off great, but a fat chipmunk has damaged some of the lower specimens, and well, that is the ugly side of gardening.

To see a tomato half eaten on the ground is discouraging, but it forces us to shrug our shoulders, cry, or become determined to try a new technique to combat the critters. Because in the end, it is worth it to bite into a fresh, juicy, flavorful home grown tomato.

On top of the chipmunk problem – the foliage on my tomato plants started to look bad just recently. I should share a photo here, but why depress myself more?

I think it is Septoria leaf spot. The leaves developed small, dark spots and it started from the bottom parts, and eventually got on many of the leaves throughout the plant.

This type of problem, the leaf spots, occurs more commonly, from what I’ve read, during heat and humidity, and lack of air circulation contributes to the issue as well.

Yesterday, I took pruners out and cut all the damaged foliage off. It took some time, but I just couldn’t stand looking at the terrible foliage.

Fortunately, it does not affect the tomato fruit. Thank God!

Next year will be a new strategy. That is the name of the game, keep trying, don’t give up.

Mikado Tomato Plants

By the way, in the photo above, that is a Mikado tomato. It is an heirloom and I grew plants from seed in April.

I transplanted them into 15-gallon fabric grow bags around Memorial day (which was the first time trying grow bags – more on that later).

They mature by August – as in now, and are indeterminate (keeps growing taller).

I should have given the plants more air circulation by spacing them out more – next season, they will be put in different places too.

Yesterday, I took that photo (above) of one Mikado tomato that is nearly perfect.

Then, I begged the gardening Gods to not allow it to get attacked by a critter, crack, or whatever. I’m scared to go look this am – as I decided to not quite pick it yet. Being hopeful.

Of course, tomatoes like sun, warmth, and as much good air flow as can be provided. I think I did well with the sun, warmth, but my mistake was not spacing them out enough. They grew very large and needed more space – so lesson learned.

Yesterday, while out pruning the nasty damaged foliage from the leaf spot (noted above), I spotted this cluster of tomatoes on another plant, called Stone Ridge (Solanum lycopersicum).

Stone Ridge Tomato Plants

As stated on the seed packet, they are dense, bottom heavy, and have sweet fruit – so true based on my experience so far.

What I found with this type is the cracking seemed to happen more on the tops (like they are that heavy and dense enough to weigh them down) but no matter, they are freaking delicious – and they are SWEET tasting.

The Stone Ridge tomato plants have weird various shapes to their fruit.

Some are pear-like (above) and some are just goofy and flatter or fatter. I like viewing the stages of them. When you touch them or hold them, they are heavy.

They must be started earlier from seed, which I did in late March.

As far as the tomato plants go, the Fox Cherry Tomato is my absolute favorite. And apparently is for my fat chipmunk freeloader too.

Fox Cherry Tomato Plants

The shape and size are just perfect for skewers, or cutting in half, because they are more like two bite-sized than one-bite sized. They are plump and perfect. And the plants are vigorous growers. Staking, twining, and supports are needed but worth it.

Every day, I go out and grab many and put them in little farmers market baskets (used for raspberries or strawberries which I saved) and set them on the kitchen island.

And every morning, my husband takes a bag full to eat as snacks at work. That is the most rewarding part of it – how much he loves them.

Usually the heat and humidity is good for tomato plants, but it can help to introduce some problems, such as leaf blights, like the Septoria leaf spot, I believe was the problem on mine this month.

I won’t let it stop me though – just keep improving the process next year.

In the photo above, there is the Bumble Bee Mix cherry tomato next to the Fox cherry tomato, to compare.

Bumble Bee Mix Cherry Tomato Plants

These are fun to grow as well. The have a unique striped patterns, are mild sweet, and smaller than the Fox variety.

They turn various colors, either yellow, purple, or just mixed. Sometimes it is hard to know if they are ready, but I still love them.

Both the Fox and Bumble Bee will be on my growing list again in 2019.

Another plant I grew this year is called, Matchbox Pepper (Capsicum annuum), and I LOVE these for the ease of growing and plant size.

Matchbox Pepper Plants

Why are they so great?

Because they are absolutely perfect for hanging baskets.

The peppers are tiny (and supposed to be spicy but we haven’t tasted one yet – probably will this weekend as they are reddening now), and they are decorative.

But the fact this plant stays compact makes them just wonderful in hanging baskets.

They, like some of the tomato plants, had to be started early inside. They mature 75 days from transplant. They just started to turn red last week.

Now, I just have to learn how to dry these hot peppers, or make some chili this weekend.

And another bonus about pepper plants is that critters tend to stay away from the hot ones. And the fact the plant is in a hanging basket keeps them up high and potentially away from critters looking for a tasty treat.

Upcoming Workshops

If you want to learn my process on how I overwinter my tropical plants by storing root bases, tubers, rhizomes, corms, etc, the dates have been published on WORKSHOPSCT.com for early September.

I am scheduling it early so people may prepare ahead of frosts. Sign up is requested for headcount but it is a simple ‘pay at the door’ setup for this session.

I’m in love with the big foliage of the tropical plants (canna, elephants ears, and red banana plants) which, as I noted, is flourishing in this heat, humidity, and rainfall.

Another bonus about tropical plants is they remain gorgeous all the way into October, and tomatoes for that matter sometimes continue into early October as well.

Well, that’s all for today – I have to get busy again.

I’ll let you know if that juicy Mikado tomato made it – and if yes, it is my lunch today.

AS ALWAYS, I so very much enjoying reading your posts and blog! And your marketing media picture skills (as I call them). ! Superb!!! Thanks for the information and beautiful pictures! I am always learning from you !

Hi DT! Thank you for reading my post and compliments on my photos – I am very addicted to taking photos of plants – that is for sure. I’m looking forward to seeing you at the next big workshop cause you always bring creative ideas as well. I learn from my fav attendees all the time. Cathy T.

Thanks for sharing your pics and comments about unusual (for me) tomato varieties. I too planted tomatoes too close for this year’s “monsoon season”. Sun out today and house company departed….heading out to see what I find in tomato patch. I do know there is a woodchuck around 😡. Hoping there are enough for us and the critters.

Hi Betty! How did you make out with your tomato patch? It has been a critter and weed year here in CT with all the heat and humidity. I had more crabgrass than ever by my mailbox to the point it consumed my bed there. Will be a job to get it all out. I also saw the “fat chipmunk” running by last night with a yellow cherry tomato in his mouth – LOL. Good to hear from you – hope your plants are doing well! Cathy T.
